Dillow is an English surname whose origins can be traced back to the medieval period. The name is recorded in a variety of spellings that indicate its evolution over centuries, and it is now most commonly found in the United States, particularly in West Virginia where it exceeds national frequency by a large margin.

The earliest known reference to a name closely related to Dillow appears in the 1250 Hundred Rolls for Oseney in Oxfordshire, where a Henry del Ewe is listed as a dweller by water. The construction de l’eau suggests a Norman locational origin meaning “dweller by the water.” This early appearance, combined with later evidence from the 16th and 18th centuries, supports a Norman and medieval provenance for the surname.

From an Anglo‑Saxon perspective, the name is often linked to the Old English personal nickname *Dill*, itself a short form of compound names starting with *Dēor*, meaning “dear” or “beloved.” The addition of the suffix -ow is understood to denote “son of”, making the name interpretable as “son of Dill” or “descendant of the beloved one.”

Another set of hypotheses points to Old English terms such as *dyle* (a type of aquatic bird), *delf* (a miner or quarryman), or *dol* (meaning dull or stupid). These variations, which have given rise to spellings such as Dyll, Dull, and Delle, illustrate the frequent phonetic and orthographic changes that surnames underwent before standardisation.

Geographical interpretations have also been proposed, notably the combination of dic (ditch or dyke) and halh (nook or corner), implying a place situated near a ditch or at a corner. Alternatively, a derivation from Old Norse dill (the herb) and lo (meadow) suggests a name for a meadow where dill grows.

In the 16th century, a spelling Joone Dyllowe was recorded in London in 1584, and the first documented instance of the spelling Dillow appears in a christening record for Joane Dillow dated 24 August 1589 at St. Botolphs Church, Aldergate, during the reign of Queen Elizabeth 1. Subsequent records demonstrate the name’s continued use and its adaptation: Dillow appears in 1679 at Clerkenwell, Dillo in 1714 at Westminster, and Dilew in 1820. In 1755, a witness named Benjamin Dilleau was recorded at Spitalfields Christchurch, reflecting the influence of Huguenot refugees on the surname’s development.

By the 18th and 19th centuries the surname had entered the New World. Census data for the United States indicate that Dillow is most prevalent in West Virginia, where it is sixty‑one times more common than elsewhere in the country. States such as Ohio, Kentucky, Illinois, and Indiana exhibit relatively higher concentrations, and the name is also present, though less frequently, in Canada, England, and Australia.

In addition to the various historical spellings—Dill, Dillon, Dillan, Dyllan, Dyllon, Dillowe, Dilloe, Dilow, and Dyllow—the surname can occasionally appear as a middle or first name. Its orthographic variations have likely been shaped by emigration, immigration, and Anglicisation processes over time.

Among the modern bearers of the name is Harry Conrad Dillow, a published poet and professor emeritus holding two Doctor of Philosophy degrees. His scholarly achievements exemplify the continued presence of the Dillow surname within contemporary intellectual circles.
